Endless Summer Bloomstruck Hydrangea Shrubs for Sale Online

The Endless Summer 'Bloomstruck' Hydrangea (Hydrangea macrophylla) reblooms every July and August producing gorgeous mophead flower heads that vary from violet-blue to rose, depending on the soil. Blooming on both old and new wood, these astonishing blossoms are held up by unique red stems, a welcome contrast to the accenting green foliage. After the flowers fall in the autumn, these green leaves darken to burgundy to match their stems.

Like most hydrangeas, this bigleaf shrub enjoys moist, well-draining soil and can tolerate full sun but prefers partial shade. I would suggest you adjust sun exposure depending on your local climate. In these conditions, this Endless Summer Hydrangea can grow up to 5 feet tall and wide.

Since the soil pH determines the color of your flower clusters, here are a few tricks to achieve your desired hue. for blueish-purple blooms, add aluminum sulfate to make the soil more acidic. Deep Rose flowers require a slightly higher pH. I find that the addition of lime to the surrounding soil accomplishes this.

The Bloomstruck Hydrangea does great as a hedge or a centerpiece to your border garden, giving both privacy and color to your yard all summer long. Be mindful, however as these are deciduous shrubs and the aforementioned privacy will dissipate in the fall. Snip off a few of these vibrant blue flower heads to bring some life into your house.

How to Care for Endless Summer Bloomstruck Hydrangea Shrubs

Before you buy an Endless Summer Bloomstruck Hydrangea, make sure to read about the recommended care instructions to keep this plant healthy and flourishing.

How should I plant my Endless Summer Hydrangea?

How should I plant my Endless Summer Hydrangea?

Plant your Bloom Struck Hydrangea in a hole that is twice as wide as the root system, but no deeper. Cover with well-draining soil and give your plant a good watering. These resilient plants can survive in clay or sandy soil, given that they receive plenty of water. To get a head start on these beautiful plants, opt for the 3-gallon pot for your garden. For gardeners in zone 5, plant your hydrangea where it can be sheltered and protected during the winter months.

How should I water my Bloomstruck Hydrangea shrubs?

How should I water my Bloomstruck Hydrangea shrubs?

As mentioned, Endless Summer Hydrangeas love moist soil so be sure to water your shrub at least weekly to maintain this. During the first season, it is best to water it more often in order to support an extensive root system that will encourage the hydrangea’s well being.

How do I fertilize an Endless Summer Bloom Struck Hydrangea shrub?

How do I fertilize an Endless Summer Bloom Struck Hydrangea shrub?

To encourage blooms, use a fertilizer that is high in phosphorus such as Jack’s Classic Blossom Booster. An organic alternative would be as compost or manure. Homemade compost is easy to make and fantastic at giving your plants the nutrients it needs.

What type of mulch should I use for my Bloomstruck Hydrangea?

What type of mulch should I use for my Bloomstruck Hydrangea?

Before winter begins, it is important to protect the roots from the harsh climate. I propose an organic material such as straw or mulched leaves for preservation. When spring comes, surround your hydrangea with ground hardwood or cypress hardwood mulch to retain moisture. Be sure to leave a small gap between the stem and the mulch to prevent rot.
